Halpern (Flashes of Creation), a physics professor at Saint Joseph’s University, delves into the multiverse in this thought-provoking if challenging offering. He opens with a superb introduction to the concept of the multiverse, explaining that it stems from physicist Hugh Everett’s hypothesis that measuring quantum states “splits” reality, with every possible outcome constituting its own world. The idea is not without its critics, Halpern notes, observing that because there’s no agreed upon method for detecting or measuring alternate universes’ existence, some scientists decry the multiverse as unfalsifiable. The bulk of the book consists of a broad scientific and philosophical history of the ideas underlying the multiverse, covering Albert Einstein and Niels Bohr’s disagreements over observers’ role in quantum mechanics and physicist Paul Steinhardt’s 1980s work suggesting the early cosmos might have been “a bubbling froth of multiple expanding universes.”Halpern sometimes loses focus, however, as when he takes a lengthy detour examining Friedrich Nietzsche’s belief in the “endless repetition of events throughout the eons.” Though Halpern does his best to make the science accessible (he likens Everett’s understanding of the multiverse to “an ever-flowing river with many persistent branches”), his valiant efforts come up short when faced with the complexity of string theory and a proposed “eleven-dimensional brane world.” Still, the curious will find much to ponder.

From the Publisher
A splendidly lucid narrative of a century’s developments in relativity, particle physics and cosmic speculation."—Wall Street Journal
“A lively synthesis of millennia of scientific debate.”—Scientific American
“Halpern is a lively, clear writer… this is a terrific guide to mind-bending physics.”—New Scientist
“This expert untangling of complicated concepts will kindle curiosity and awe for quantum physics. An excellent recommendation for both science-fiction enthusiasts and readers of popular nonfiction.”—Library Journal (Starred)
“A superb introduction to the concept of the multiverse… the curious will find much to ponder.”—Publishers Weekly
“Illuminating discussions of a host of complex concepts… cutting-edge physics for the educated layperson.”—Kirkus
“The implications of quantum mechanics (a scientific theory that has passed every experimental test of it so far devised) are often bizarre — but none more so than its suggestion of a multiverse of parallel worlds. Once found only on the pages of philosophy journals and in the stories of science fiction magazines, the multiverse concept is now being taken seriously by no-nonsense physicists. In clear, accessible prose, Paul Halpern’s The Allure of the Multiverse explains how this evolution in our scientific understanding of reality has occurred.”—Paul J. Nahin, University of New Hampshire, and author of Time Machine Tales
“A rich and rewarding history of one of the most astounding ideas in physics and astronomy: the multiverse. Don't believe that other universes might be residing right beside our own, hidden from view in other dimensions? Paul Halpern will convince you to take a second look.”—Marcia Bartusiak, author of Black Hole
“As soon as you contemplate, ‘What if?’ you enter the multiverse. Paul Halpern’s The Allure of the Multiverse serves as a masterful guide. Whether you're a curious novice or a seasoned science enthusiast, this book offers a cogent exploration of the maddening infinities our minds can create.”—Chris Ferrie, author of Where Did The Universe Come From? And Other Cosmic Questions
“The multiverse is a staple in today’s science fiction, but as Paul Halpern shows us, the idea of a multitude of universes has a rich history, with scientists and philosophers debating its merits for centuries. From Friedrich Nietzsche’s musings on ‘eternal return’ to Hugh Everett’s mind-bending interpretation of quantum mechanics, The Allure of the Multiverse blends history and physics while it both provokes and entertains.”—Dan Falk, author of The Science of Shakespeare and In Search of Time
“In The Allure of the Multiverse, Paul Halpern takes a deep dive into the history, philosophy, and personalities behind this strangest of ideas. An informative and entertaining read, whichever corner of the multiverse you inhabit.”—Will Kinney, author of An Infinity of Worlds
“Befitting a discussion about the Multiverse, Paul Halpern’s latest book contains multitudes. Covering topics from Quantum Mechanics to General Relativity, from the subatomic realm to the edge of the universe (and beyond!), this fascinating and engaging book will expand your mind into new dimensions.”—James Kakalios, author of The Amazing Story of Quantum Mechanics
“Halpern is a lively, clear writer… this is a terrific guide to mind-bending physics.”—The Michael Shermer Show

Science writer and physicist Halpern (Saint Joseph's Univ.; Flashes of Creation) taps into the current fascination with alternate realities. A growing number of movies, TV shows, and novels point to increased understanding and questioning of multidimensional worlds. Halpern posits the possible existence of parallel universes via conceptual frameworks from geometry, cosmology, and physics—some of them widely accepted, others already discounted, and many currently under critique. He connects the research of Newton, Einstein, and Hawking to that of dozens of other historical and modern figures. Proceeding through decades of observation, experimentation, and simulation, the book charts the movement toward and then away from from a single, unified theory of the universe. VERDICT This expert untangling of complicated concepts will kindle curiosity and awe for quantum physics. An excellent recommendation for both science-fiction enthusiasts and readers of popular nonfiction.—Catherine Lantz

The author of Einstein’s Dice and Schrödinger’s Cat returns with another examination of difficult scientific concepts.
Halpern, a Guggenheim fellow and professor of physics at Saint Joseph’s University, begins by introducing the James Webb Space Telescope, launched in late 2021, whose instruments reach “faint, distant galaxies from the nascent era of the universe” and send back “vivid photo evidence.” By definition, our universe includes everything, so an “alternative” universe makes no sense; no one will ever see one. Yet multiverse models offer enticing mathematical and theoretical ideas. Such concepts were no secret to 19th-century mathematicians, but they entered the mainstream in the 20th when the physics community reluctantly accepted a fourth dimension to make sense of Einstein’s relativity. Then, scientists confronted quantum theory, which works so brilliantly, at least theoretically, that the traditional view (propounded by quantum pioneer Niels Bohr) requires physicists to accept that quantum phenomena occur in a “black box.” Although this remains the standard interpretation, plenty of geniuses yearn to look inside the box. A dedicated teacher, Halpern explores half a dozen relevant topics including string theory, supergravity, and M-theory. Readers anxious to plunge ahead may want to reserve their decision until they sample the author’s explanation of a simple high school physics term: the vector. Halpern’s analysis is not for the innumerate, but dedicated readers will be rewarded by illuminating discussions of a host of complex concepts, a penultimate chapter on the physics of time travel, and a conclusion that describes alternate universes portrayed in movies and TV. Halpern’s 2021 book, Flashes of Creation: George Gamow, Fred Hoyle, and the Great Big Bang Debate, is a delightful and accessible popular science book. This follow-up is an ingenious slog that may enlighten those with college courses in relativity and quantum theory under their belts.
Cutting-edge physics for the educated layperson.
